Setting up the correct resolution on RevPi

[TonyR]

Hello,

we got a problem with the display resolution on our RevPi. First the resolution was fine when we plugged in a 1200 x 800 touch screen without any additional drivers necessary. However after a while the resolution defaults to 640 x 480. We didn't change anything in a config file. The PC is now in production without access to internet and we don't really know what we can do to setup the correct resolution.

Any ideas?

Btw. In this guide most of the screenshots do not load so it's hard to follow: https://revolutionpi.de/tutorials/revpi ... instellen/

Greetings
Tony

Hi Tony,

You can modify /boot/config.txt.
You will find this there:

Code: Select all

#hdmi_group=1
#hdmi_mode=1

Remove both # and change hdmi_group=2
(group=1 means PAL capable resolution, 2 are "real monitors”)

From now on, the RevPi and the monitor should agree on a reasonable common mode.

You can also set a resolution using "sudo raspi-config" → Advanced Options → Resolution.

If you still have problems, please send the /boot/config.txt.

Regards
Johannes
